FOLDING CHAIR.

SPECIFICATION forming part of Letters Patent N 0. 737,680, datedSeptember 1, 1903.

Application filed September 29, 1902- Serial No. 125,307. (No model.)

T0 at whom it ntay concern.-

Be it known that I, OAsPAR M. WAGNER, a citizen of the United States,residing at Ohicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Folding Ohairs,of whichthe following is a specification, reference being had to theaccompanying drawings.

This invention relates to improvements in folding chairs and primarilyto rockingchairs.

In Letters Patent No. 700, 266, granted to me May 20, 1902, is shown anddescribed a folding rocking-chair, and my present invention involvescertain advantageous features of construction over said patented chair.Said former chair while strong and durable and easily folded was notprovided with front legs arranged to resemble the ordinary rigid chairstructure, but, on the contrary, was provided with a system of long andshort diagonal braces that constituted the means for supporting thefront portion of the chair. It is desirable that, so far as possible, afolding chair be made to conform in appearance to the ordinary rigidchair construction; and one of the objects of my present invention is toso construct a folding chair as not to be markedly different inappearance from such rigid chairs, which I am enabled to do ashereinafter specifically described and without impairing its folding orcollapsible quality.

Another object of my present invention is to provide a separateconnection for each rear leg instead of securing such legs directlyopposite the seat-frame by the pivots that secure the back-frame to theseat-frame. The advantages of such construction will be hereinafterpointed out.

In the accompanying drawings, Figure l is a side elevation of myimproved chair in position for use, and Fig. 2 is a side elevation ofthe chair in a partially collapsed or folded position.

Referring to the figures of the drawings, A indicates a seat-frame ofordinary construction, to or upon which a seat of any approved charactermay be attached, the seat proper being indicated by a.

B indicates the back-frame, the side bars of which are pivoted bybolts 1) to the outer faces of the side bars of the seat-frame A,

near the rear ends of such seat-frame. As shown, these side bars of theback-frame are provided with downwardly extending portions 0, projectingsome distance below the seat-frame.

0 indicates one of a pair of front legs, each pivoted at (Z near itsupper end to the side and near the front edge of the seat-frame A.

D indicates one of a pair of rear legs, each pivoted near its upper endby a pivot e to one of the downwardly-extending portions 0 of theback-frame.

E indicates one of a pair of braces-one being provided at each side ofthe chairpivotally connected at its forward end by a pivot f to one ofthe front legs 0 a short distance below the seat-frame and pivotallyconnected at its rear end to one of the side bars of the back-frame by apivot g. This pivot g, as will be seen by reference to Fig. 1, isconsiderably in rear of the pivot e that connects the upper end of theleg D to the extension of the back-frame when the chair is in positionfor occupancy. lVith the chair in such position the brace E restsagainst the upper end of the leg D and a firm locking of the parts inthis position is effected, the holding or looking effect being increasedby the weight of the occupant.

In the chair of my former patent a single pivot at each side of thechair was employed for uniting the back-frame and one of the rear legsto the seat-frame, but I have found it to be an advantage to employ tworelatively short independent pivots, as b and e, rather than a singlelong pivot, for by the use of a separate pivot for attaching the rearleg I am enabled to attach the seat at the desired angle to theback-frame and at the same time preserve the proper inclination of theback-frame to render the chair as a whole comfortable to the user, andneither the length nor inclination of the rear legs need be varied toaccommodate the angle at which the seat may be fixed.

The rear and front legs must, of course, be so connected as to hold themfrom turning on their respective pivots independently of each other.Such connection is furnished, as shown, by rockers F, connected bypivots h to the front legs and by pivots 11 to the rear legs.

-3y this invention I provide a chair differing but little in appearancefrom the ordinaryconstruction of rigid chairs and which is so connectedtogether as to be readily and easily turned or folded so as to occupybut little space.

That which I claim as my invention, and desire to secure by LettersPatent, is

1. In a folding chair, the combination of a seat-frame, a back-framepivotally connected therewith and having extensions projecting below theseat-frame, a pair of rear legs piv: otally attaehed'to such extensions,a pair of front legs pivotally connected with the seatframe, a pair ofbraces each pivotally attached at its forward end to one of the frontlegs and at its rear endto the back-frame above the point of attachmentof said back-frame to the seat-frame, a stop for each of said braces toabut against, and means at each side of the chair for connecting thefront and rear legs together, substantially as specified.

2. In a folding chair, the combination of a seat-frame, a back-framepivotally connected therewith and having extensions projecting below theseat-frame, a pair of rear legs pivotally attached to such extensions, apair of front legs pivotally connected with the seatframe, a pair ofbraces each pivotally attached at its forward end to one of the frontlegs and at its rear end to the back-frame above the point of attachmentof said back-frame to the seat-frame and resting against the upper endsof the rear legs when the chair is in position for use, and means ateach side of the chair for connecting the front and rear legs together,substantially as specified.

3. In a folding chair, the combination of a seat-frame, a back-framepivotally connected therewith and having extensions projecting below theseat-frame, a pair of rear legs pivotally attached to such extensions, apair of front legs pivotally connected with the seatframe, a pair ofbraces each pivotally attached at its forward end to one of the frontlegs and at its rear end to the back-frame above the point of attachmentof said back-frame to the seat-frame, a stop for each of said braces toabut against, and rockers pivotally attached to the lower ends of thefront and rear legs,

substantially as specified.

4. In a folding chair, the combination of a seat-frame, a back-framepivotally connected therewith, front supporting-legs pivoted to theseat-frame, rear supporting-legs pivoted to the back-frame, a pair ofside braces each pivotally attached at its forward end to one of thefront legs and at its rear end to the back-frame at a point above and inrear of the pivots for the upper ends of the rear legs when the chair isin position for use, a stop for each of said braces to abut against, anda connection at each side of the chair attached to the front and rearlegs, substantially as specified.
